Examples of human ecological civilization

For the sticky copy of the stream, I will not comment. Examples of ecological civilization, to put it bluntly, is an example of man and nature living in harmony, our country is mostly negative, nothing worth blowing. As for examples, such as Japan, South Korea and other countries of the example of the fisheries, why our country around the fisheries are going extinct, other people year after year a bumper harvest, this is an example of how to do ecological civilization. And then there's Yellowstone Park in the United States.
